Randy, I would stop trying to feed your haddoni for awhile. I can't remember the last time I specifically fed my blue one. I've had him since 2003. From what I've read of the posts, it sounds like you have a stressed out haddoni. Especially, with the reproduction response. I wouldn't worry about sand, remember in the wild these guys know how to deal with this, so the same should be said in a reef tank. The moving and climbing on rocks is another hint at a stress response. Before I had backup power, temperature drop and lack of flow would have my haddoni moving around for a day or two. Finally, it would sit down attached the underside of a rock in the sand. That's when its finally happy. The closing up during lights on happens. Don't know why. I would just stop transferring it and let it settle in.
